Report: CVE-2026-42512 - Remotely triggerable out-of-bounds heap write in dhclient

CVE ID :CVE-2026-42512 Published : April 30, 2026, 7:58 a.m. | 1 hour, 11 minutes ago Description :As dhclient is building an environment to pass to dhclient-script, it may need to resize the array of string pointers. The code which expands the array incorrectly calculates its new size when requesting memory, resulting in a heap buffer overrun. A specially crafted packet can cause dhclient to overrun its buffer of environment entries. This can result in a crash, but it may be possible to leverage this bug to achieve remote code execution.
